hey guys new to the forum but just doing a little homework. Im looking at an 02 xc sp 700. it has 3000 miles on it. How long do these motors last? And are they really faster than the competition in the early 2000s? Anything in particular to look for on this sled? I just had my skidoo mxz 800 blow up with only 4000 miles on it and dont want this problem again. any help would be appreciated! thanx

Welcome to the forum! The 700 is probably the best of the big block Liberty engines, it has a lot better reputation for holding together a lot longer than it's bigger brother 800.

4000 miles can be a lot of miles on any two-stroke snowmobile, at that miles I would really look hard at doing some preventive maintenance in the top end. Some guys go a lot farther than that with no issues, others break theirs a lot sooner. You pays your money and you takes your chances.

the 700s were awesome motors. my 98 had a million miles on it when i lost a screw for the oil pump and it fell off while riding i then got an 01 and it is still running today. they both had/have pipes, reeds, and unionbay heads.

Thanx guys, i did some other homework and i seem to find a lot of these sleds with high miles, that means they must hold together! my buddy bought an 03 sks 700, and i am impressed with the power. I think its faster than my mxz ever was! As long as this sled is as clean as its supposed to be, I know what ill be riding... Thanx again guys!

the 02 700 was probably the best made has the most power and bullet proof.they down tuned the 03 and up for whatever reason guessing because it was embarissing there 800.3000 miles is nothing for that motor.
